write your full name Amoeba sisters DNA Structure and Function Watch the video, fill in the blanks below. Actually watch the video... 1. DNA stands for deoxyribose nucleic acid2. A clone is an identical copyof the original.3. Clones are exactly the same as the original because the genetic materialis the same.4. One could say DNA is the most important molecule of life.5. DNA controls all of your traits.6. Cells can't function without DNA.7. What are some traits DNA controls? - DNA controls how tall you will be. - what coloryour eyes are. - What color your hair is. - or even if you are at risk for certain diseases9. Is DNA not turned on all of the time in all cells.10. The ability to turn genes on and off is called gene regulation11. DNA is a type of nucleic acid12. The building block (monomer) of nucleic acids are nucleotides13. Deoxyribose is a sugar Nucleotide label the parts of the nucleotide; base, deoxyribose, and phosphate group phosphate group deoxyribose base 14. The most important part of the nucleotide is the base because it is what actually codes for the traits.15. How many bases are in DNA? four16. What are the bases in DNA? A - Adenine T - Thymine G - Guanine C - Cytosine17. How do the bases pair up and what is the saying to remember each pair? Pair: Awith T Saying: Applesin the tree Pair: Gwith C Saying: Carsgo in the garage18. How many strands does DNA have? two19. What holds the strands together? hydrogen bonds Label all parts of this DNA strand Word Bank: adenine, cytosine, guanine, bonds, phosphate, sugar, thymine sugar phosphate guanine cytosine thymine adenine bonds 20. DNA is a double-helix, meaning the strand is twisted.21. DNA is found in the nucleusof your cells, not the cytoplasm.
